I used this on my friends bike when She got a flat on the bike trail. It worked excellent and I fell in love with it right away!!!. I previously had a different one without the squeeze trigger, safety, or compartment to keep the cylinder. I absolutely hated it and was actually scared to use it. No more fear of using Co2 cylinders here!

The safety valve works great and the squeeze trigger allows you to put in the exact amount of air you want.

Plus the compartment for the cylinder keeps your protected from the cold once the Co2 is released.

I highly recommend it!! I don't usually write a review, but this product exceeded my expectations. It's a must have!

My old Innovations Proflate (called a 16 back then) lasted three years. A quick and effortless way to get back on the road with little hassle. A work of caution, try not to drop it. I was switching out seatbags in my garage and accidentally dropped my Proflate on the cement garage floor. I keep mine loaded with one cartridge stored upside down in the inflator. I had a flat a few days later and it was a little hard to get air into my tire. I had to use 2 cartridges. I thought it was user error, as I don't use it that often. Around two weeks later, another flat. This time the little red indicator that pops out showing the cartrige is loaded, did not pop out and it immediately begain leaking air. I used another cartridge and working fast, managed to get emough air into my tire. I think when I dropped it I damaged something, so these devices are not bullet proof. So, if you drop yours, test it out to make sure it still works.

My inflator leaks all the CO2 out using a threaded or non-threaded cartridge. When you puncture the cartridge be ready to inflate your tire because the contents will be gone in a minute. Don't plan on using it more than once.

If you must use CO2, then buy this because it works great for the mechanically inept like me. Best feature is that you can dispense the gas with control. Yeah, the handle's big but if you use threaded cartridges, you don't need it. Even with the handle, it's still small enough to fit in a seat post bag. Second-best part is that you don't need to read the directions. Just be standing beside the road, holding your wheel with the repaired tube and tire with aplomb, and you'll figure it out.

I carry one of these on all three of my bikes. I never really thought about flats much, I did have one on my Mtn Bike last summer. I was two miles out so I just walked the bike back. Otherwise I confess to being very lucky, almost 7K street miles since my last flat!! But then I got to thinking that I should be better prepared so I bought one of these inflators for each machine and I now carry a spare tube, levers and this gizmo in a seat bag on each machine. Well last Saturday I was flying down a hill on my TREK Madone, ran over something and ended up with a pinch flat. This time I was about 10 miles out. It was getting dark and I was pretty well used up so walking back wasn't an option. So out comes the tire repair gear, I pulled the old tube out and confirmed it wasn't a puncture, installed the new tube and remembered I had just stuck the inflator into the seat bag without the instructions. The good news is that this thing is simple to use and one cartridge inflated the tire to over 110 psi, I was on my way in minutes! Don't leave home without one, a spare tube and an extra CO2 bottle!!
